Title

Measuring Vitamin C

Problem Scenario

People need to know which cooking method destroys more nutrients and vitamin C

Broad Question

Which cooking method destroys more Vitamin C

Specific Question

Does boiling or microwaving destroy more vitamin c in vitamin C solution.

Hypothesis

I think microwaving will destroy more vitamin c in vitamin C solution.

Microwaved	Boiled	Untouched	Amount Destroyed	Results
8	11	15	7 M	Microwaving
9	10	14	8 M	Microwaving
8	10	14	7 M	Microwaving
8	11	16	7 M	Microwaving

Microwaving destroys more Vitamin C

Variables

General Plan

For this experiment, I am going to see which cooking method could destroy more Vitamin C. I will
microwave one bowl of Vitamin C solution, and boil one bowl. I will use starch solution so that the iodine
will work. With iodine, I will measure the amount of vitamin C in each method: Microwaved, Boiled, and
Untouched. I'll find the difference of each method to the untouched, and see which method needs less drops
of Vitamin C, and which one destroys more vitamin C after the original.

Potential Problems And Solutions: Not enough vitamin C solution. Solution: make more. Not being able to measure vitamin c. Solution: Talk to Mr. Biche

Safety Or Environmental Concerns:

Iodine in eyes. make sure nobody drinks it thinking its drinkable.

Experimental Design

(add the correct headings from the experimental design page before beginning)

.

What is your experimental unit?

This is the base unit of your experiment, for example, one plant, one ice cube, one dish. It is the thing you will be measuring.
Ill be measuring which cooking methods could destroy more vitamin C in a vitamin C solution. Experimental unit is vitamin C solution.

Number Of Trials:

This is how many times you will repeat the experiment.
I will repeat the number of trials twice and record the average for each result.

Number Of Subjects In Each trial:

This is the number of different treatments you will use. For example, if you are comparing rust formation using salt and no salt, there would be 2 subjects in each trial. If you were comparing rust formation with no salt and three different amounts of salt, then you would have 4 subjects in each trial.
3. Untreated, Boiled, Microwaved.

Number of Observations:

How many measurements will you take for each experimental unit times the number or trials
3 times for each method.

When data will be collected

Looking for an actual date or dates here. This is requiring you to commit to your project.
March 16 I will do my experiment,

Where will data be collected?:

Be specific.
In my house.

• 1-quart (l-liter) jar
• spoon
• 4 baby-food jars

Vitamin C	1 jug	hannafords/shaws	2.79

Iodine	1	Cvs	2.00

Distilled Water	1/2 Cup	Got it...	0.00
StoveTop	1	home	0.00
microwave	1	home	0.00
dropper	1	got it	0.00

Procedure

CAUTION: Keep the iodine out of reach of small children. It is poisonous and is for external use only.

1. Prepare a standard vitamin C solution by:
   • crushing the vitamin C tablet (place it between two sheets of wax paper and hit it gently with a hammer).
   • pouring 1/2 cup (125 ml) of distilled water into the quart (liter) jar.
   • adding the crushed vitamin C powder to the water in the jar.
   • stirring until the powder dissolves.

1. Pour equal portions of the standard vitamin C solution into 2 3 bowls
2. With the marking pen, write "A." "B," "C," and "D" on pieces of masking tape and tape one label to each jar.
3. Add 1 teaspoon (5 ml) of the starch solution to each jar.
4. Place jar A on the sheet of white paper.
5. Fill the eyedropper with tincture of iodine. Slowly add the iodine in the eyedropper to jar A. counting each drop added (see Figure 7.1). Swirl the jar after each addition of five drops. Continue to add the iodine until the jar's contents remain a blue-black color.
6. Record the number of drops required to turn the jar's contents this blue-black color.
7. Repeat the procedure using jars B, C, and D.
8. Add the results for the four jars and divide by four to compute the average number of drops of iodine needed to react with the 25 mg of vitamin C in each jar. Note: This number will be used to calculate the concentration of vitamin C in other substances.

Time Line

First I will do my first test. Uncooked i will put some starch solution into the Vitamin C solution, next I will take the dropper and count how many drops it takes to change the color completely from foggy to a light purple/blue. I will record the number.
Next I will do my 2nd test. Microwaved, I will put some starch solution into the Vitamin C solution, next I will take the dropper and count how many drops it takes to change the color completely from foggy to a light purple/blue. I will record the number.
Next I will do my 3rd test. Boiled on the stove I will put some starch solution into the Vitamin C solution, next I will take the dropper and count how many drops it takes to change the color completely from foggy to a light purple/blue. I will record the number.

Conclusion

I can't decide whether I reject or accept my hypothesis, because my experiment did not work.

Discussion

Benefit to Community and/or Science

People (Were suppose) to know which method of cooking could be better for you. Cooking on a stove-top and microwaving are both common everyday things people use. If they knew which one was better for you, or which one destroyed less Vitamin C, they would know which one was healthier, and more beneficial.

Background Research

1. Pour equal portions of the standard vitamin C solution into 2 3 bowls
2. With the marking pen, write "A." "B," "C," and "D" on pieces of masking tape and tape one label to each jar.
3. Add 1 teaspoon (5 ml) of the starch solution to each jar.
4. Place jar A on the sheet of white paper.
5. Fill the eyedropper with tincture of iodine. Slowly add the iodine in the eyedropper to jar A. counting each drop added (see Figure 7.1). Swirl the jar after each addition of five drops. Continue to add the iodine until the jar's contents remain a blue-black color.
6. Record the number of drops required to turn the jar's contents this blue-black color.
7. Repeat the procedure using jars B, C, and D.
8. Add the results for the four jars and divide by four to compute the average number of drops of iodine needed to react with the 25 mg of vitamin C in each jar. Note: This number will be used to calculate the concentration of vitamin C in other substances.

Abstract

For this experiment, I tried to measure the amount of vitamin C Microwaving and Boiling destroyed. I boiled, microwaved, and left one untouched. I measured the amount in the untouched first, and then the cooked ones. I saw the amount cooking and microwaving destroyed, and could tell which one destroyed more, and recorded it.
